273P/Pons-Gambart - Comet C/2011 L4 (PANSTARRS) - Comet NGC 3184 - Spiral Galaxy (Herschel I - 168) NGC 3198 - Spiral Galaxy (Herschel I-199) NGC 3310 - Spiral Galaxy (Herschel IV-60) NGC 3610 - Elliptical Galaxy (Herschel I-270) NGC 3665 - Elliptical Galaxy (Herschel I-219) NGC 3675 - Spiral Galaxy (Herschel I-194) NGC 3726 - Spiral Galaxy (Herschel II-730) NGC 3729 - Spiral Galaxy (Herschel I-222) Palomar 2 - Globular Cluster Variable Stars (photometric monitoring) - RX And, Z And, U Gem, RZ LMi, FU Ori, DY Per, GK Per, ER UMa Nearby Stars (astrometric monitoring) - None
- Evening session (3.1 hrs duration). - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: -3.0°C minimum - CCD operation -30°C (at 63% average cooling). - main objectives of the session were to acquire images of a number of Herschel 400 objects in Ursa Major. Secondary objective was to acquire images selected project stars for ongoing photometric and astrometric analysis. -
